It’s funny note that despite the common complaint that the EU is ‘protectionist’ on agriculture, the only Western European countries outside the EU are even more generous than the CAP and indeed, have rejected membership in part for that reason (this is especially the case of Norway).

Anyway, this discussion misses a very, very crucial point. As things stand at present, once Brexit happens control of Northern agriculture devolves, not to Westminster, but to Stormont. So it will be the DUP handing farm subsidies, not London (at least not directly). This is going to be a huge problem for the UK in trying to negotiate foreign trade agreements.
